Internet access in Pakistan is mostly unrestricted and unfiltered. The Internet traffic is coming from two IP backbone providers, i.e., PTCL and TWA. The Internet Service Providers ISPs and backbone providers have currently deployed manual URL filtering and blocking mechanism in order to block the specific URLs containing undesirable content as notified by PTA from time to time.Many countries have deployed web filtering and blocking systems at the Internet backbones within their countries. However, Pakistani ISPs and backbone providers have expressed their inability to block millions of undesirable web sites using current manual blocking systems. A national URL filtering and blocking system is therefore required to be deployed at national IP backbone of the country.ICT R&D Fund has decided to fund the indigenous development, deployment, operations and maintenance of such a system by companies, vendors, academia and/or research organizations with proven track record.
